摘要

摘要: 2009年6、8月长江口及其邻近陆架区的网采样品中检出浮游植物9门395种（含223种硅藻与125种甲藻）。浮游植物丰度8月（3 077.15°10⁴ cells/m³）显著高于6月（107.80°10⁴ cells/m³）。随长江冲淡水势力增强，位于长江口的丰度高值区8月较6月更偏外侧。种类丰富度8月高于6月，但多样性和均匀度指数略低于6月。6月尖刺伪菱形藻和三角角藻占绝对优势，8月优势种主要有尖刺伪菱形藻、笔尖形根管藻和铁氏束毛藻。骨条藻虽非优势种，但在长江冲淡水区丰度较高。相似性分析和多维尺度分析表明，浮游植物群落组成时空差异显著。典范对应分析表明，温度和盐度是分别影响6、8月群落分布的首要因子。根据水动力和化学参数，该区浮游植物群落分布与环流变化和水团消长密切相关。

Abstract: Net-phytoplankton samples were collected from the Changjiang Estuary (CE) and adjacent continental shelf,East China Sea in June and August 2009. A total of 395 taxa (9 phyla) were identified,including 223 diatom and 125 dinoflagellate species. The phytoplankton abundance in August (3 077.15°10⁴ cells/m³) was significantly higher than that in June (107.80°10⁴ cells/m³). The high-density zone in the CE moved eastward from 31°N,123°E in June to 31°N,123.5°E in August due to the enhancement of Changjiang Diluted Water. The species richness of net-phytoplankton in August was much higher than that in June,while species diversity and evenness were slightly lower than that in June. Pseudo-nitzschia pungens and Ceratium tripos were the dominant species in June. However,P. pungens,Rhizosolenia styliformis and Trichodesmium thiebautii dominated in August. Skeletonema spp. had high abundance in the CE in both June and August,although it was not a dominant species. The analysis of similarity and non-metric multidimensional scaling showed a significantly spatio-temporal difference in phytoplankton community. Canonical correspondence analysis indicated that temperature and salinity were the primary variables affecting the community distribution in June and August,respectively. These data demonstrated that the distribution of phytoplankton community in the CE and adjacent continental shelf was intensively influenced by the circulations and water masses.
